Medical Applications of Monoclonal Antibodies
1. Cancer Treatment
- Targeted therapy: Antibodies bind to specific cancer cell surface proteins
- Drug delivery: Antibodies carry toxic drugs directly to cancer cells
- Immune activation: Some antibodies help immune system recognize cancer
- Examples: Herceptin (breast cancer), Rituximab (lymphoma)
2. Disease Diagnosis
- ELISA tests: Detect specific proteins or pathogens in blood
- Imaging: Fluorescent antibodies highlight diseased tissue
- Blood typing: Determine ABO and Rh blood groups
- Pathogen detection: Identify bacteria, viruses in samples
3. Pregnancy Testing
- Detect hCG hormone in urine
- Monoclonal antibodies specific to hCG immobilized on test strip
- If pregnant: hCG binds to antibodies → colored line appears
- If not pregnant: no hCG present → no colored line
